# How do you solve 39- 19= x - 4?

Jun 22, 2017

$x = 24$

#### Explanation:

First of all subtract 19 from 39

$39 - 19 = 20$

then isolate $x$ and rearrange the equation

$20 + 4 = x$
remember when you bring 4 to the other side the sign changes.

Here it was $- 4$ which you change to $+ 4$

finally you add both the numbers $20 + 4 = 24$

hence $x = 24$
